We did a round of Humaworm, and got very good results, and are now taking DE until we can take Humaworm again. You do feel die off symptoms when on DE, but I have seen TONS of worms in my poo and I seem to have more energy then usual. I know i have worms in my head, however the Humaworm really helped get some of them out (I blew some out of my nose, and continue to blow them out every now and then and the pressure in my head is less) and am hoping to get the rest out with our next round. You can contact them and ask questions, I know finances are limited but for a whole month that included what? 25 different herbs in it was only 40. I know some don't think herbs work, but I have not seen very many people complain about how well it does.
